- Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed October 29, 1906. Serial No. 341,114.

- .This coupling or reach` has heretofore been pivotally connected to the rear end of the fronttruclgand this arrangement has proven particularly objectionable, for the reason that when the front truck is turned withl respect to the rear truck, the distance between the bolsters is shortened. The result is'that' said bolsters must slide.V beneath the load located thereon, or the bolster bolts will bend or break. It has been proposed to 'connect tion is to provide a vehicle of the a'bovefde-` scribed character, in whichv the coupling 1s so connected to the truclrswthat the turning ofV said trucks will effect no variation of distance between the bolsters, and consequently no shifting of the load will take place on the latter, said coupling or reach moreover being separate from the bolsters, so as to not interiere with their movement, and permitting the employment of the vehicle with or without them. Y

Another object is to provide'a structure that is in the nature `of anV improvement on the vehicle disclosed in a former patent granted to me January 23, 1906, No. 810,492, though there arefeatures undoubtedly useful in connection with other vehicles of this type.

rlhe preferred embodiment of the invention will be understood from the accompanying drawings, in whichze- Figure 1 is a side elevation of the vehicle. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical sectional view on an enlarged scale` through the central portion of the v, e`

hicle. Fig. 4 is a cross sectional view through the rear truck. Fig. 5 is a detailsectional arate the front axles and axle bolsters. Fig. l 6, is a cross sectional view on the lines 6-6 of Fig. 2.1 Fig. 7 is a horizontal sectional view on the line 7-7 of Fig. 5.

Similar reference numerals designate corresponding parts in all the figures of the drawing. b

ln the embodiment illustrated, the vehicle comprises iront and rear trucks 8 and 9. As these trucks are substantially duplicates, adescription oi one is believed to be sufficient for both. Front land rear axles 10 are emirontf and rear sets oi' wheels 11. Secured to the rear axle, is a truck hound frame, comprising side bars 12 connected by a curved iront portion 13, and a center bar 14. The side bars 12 and the center bar 14 are secured to the axle by means of bolts 15 passing therethrough, which bolts also pass through a rear axle bolster 16 disposed over the bars.

The iront end of the frame is located u on the iront axle, and is slidable thereon, W ile a iront axle bolster 17 is located over said iront axle, and over the iront portion of the Vtraine. This latter axle bolster is held in spaced relation to the liront'axle by means of lhollow standards 18, which are maintained in position by bolts 19 passing therethrough an through the axle and axle bolster. The said bolts also serve to secure braces 2() that are convergently disposed, and are ivoted, as shown at 21 to the central barA 14. etween the axles. Wear plates 22, disposed on opposite sides o1" the front end oi the hound trame and secured to the Jfront axle and axle bolster, project in advance of the same, and f are provided with o enings 28, in which holding pins 24 can be p aced to limit the swinging movement of the front axle. The hollow standards 18, which support the front axle bolster 17, are provided with forwardly projecting spaced ears 25.

A bolster support, in the 'form of a beam 26 is located upon an intermediate portion of the frame, and is disposed transversely of the bars thereof, resting upon said bars and being suitably secured to the same. Upon this support is pivotally mounted a bolster 27 `carrying suitable stakes 27a at its ends. It will be observed that the bolsters oi both trucks are not directly ,in the center of said trucks, but are nearer the rear Wheels than the fronty wheels. In order to properly supview lthrough one of the standards that seplport the bolster throughout the limit of its ployed, on the ends of which are journaled movement, curved tracks 28 are employed, that are located over the side bars 12, their iront ends being secured to said side bars, as shown at 29, their rear ends being fastened by the bolts i5, which pass through. the rear axle bolster 1G. Se tar as thus descrilmd, the trucks are duplicates, and consequently it will be apparent that the parts above described, are readily interchangeable, and are applicable to either truck.

The draft mechanism tor the vehicle comprises an open boxing 30, secured between the iront ends oi divergently disposed linlrs 31. The rear ends of these linls are pivoted to and between the ears 25 or" the standards of the front truck. ln the boxing is slidably mounted a plunger 32, the front end of said plunger being formed, as shown at 33, to provide for the convenient attachment oi tongue or other draitt means. vfilithin the boxing and mounted on the plunger is a coiled spring 34, its front end bearing against the front end oi the boxing, its rear end boing borne against by a pin 35, carried by the plunger. Another spring 36 is located on the rear end ot the plunger, and bears against the rear end of the boxing. A pin 3'? carried by the rear end or the plunger, bears against the rear end or' the spring. Thus a yielding draft member is provided, which will absorb all shocks and jars that would otherwise be transmitted between the vehicle and the draft animals or other means i'or moving said vehicle.

The coupling or reach between the trucks comprises a plurality of sections. A pair of slidably associated sections 33 and 39 are employed, the section 33 being connected at its rear end to a cross bar 4G, having rearwardly extending ears 4i that are pivoted to and between the ears 25 of the standards et the rear truck. Braces 42 connect the ends of the cross bar 40, and an intermediate portion et the section 38. Other braces 43 are connected to the ends of the cross bar, and to a sleeve or cuil 44 tnat surrounds both sections 38 and 39. A horizontal transverse bolt 45 passes through the front ends of the braces 43 through the sleeve and the -liront end of the section 38, thus securing the parts together but permitting oi the ready detachment ot the braces 43 in case it is desired to introduce a section of a di'liierent length. An upright pin 46 passes downwardly through the sleeve and through both sections 33 and 39, thus serving to prevent the sliding movement ot both sections, the pin being detachable, however, and arranged to be passed through any of a series of openings 47 in the section 39. Another sleeve or cull surrounds both sections, and as illustrated in Fig. o, comprises separate sections 43 having upper and lower overlapping ends 49 located. above and below the sections. Another pin 50 passes through the overlapped ends, and through the sections 38 and 39, thus serving to further socure said sections against sliding movement, and yet permitting of their adjustment it desired, aid pin constituting the sole means lor securing the sleeve or cull sections to the. coupling or reach, will be evident by relerence to Figs. 3 and 6.

ln addition to the sectiinls 33 and 3), ol the reach already described., a swiiuring` seetion 51 is employed, which is connected to the section 3Q by a horizontally disposed pivot bolt 52. 'the pivotal connection. is, as clearly illustrated in Figs. 2 and 3, disposed directly adjacent to the rear end ol: the -liront truck, and the section 5l extends over the center bar i4 to a point between said bnr, and the front bolster supporting` beam 2o, as illustrated in Fig. 3. l'he upper side ol th(` center bar is reinforced by a metallic strap 52a, and the underside olI the support 2o is provided with a suitable wear plate 53. rthe pivot bolt 54, which secures the lront bolster 27 in place, passes through the liront bolster support, through the iront end o't the swinging section 5l ol" the reach or coupling, and through the center bar 14, thus securely holding the parts in position, vet permitting the tree movement ot the bolster with respeet to the reach and the bolster constituting no part of the means ttor securing the reach to the front truck, so that even ii' the bolster is removed, as is sometimes the 'n.se, the vehicle running` gear is still complete.

A brake is mounted on the rear truclr, and for this purpose, a roch sha/tt 55 is employed, which is disposed transversely ot the center `and side bars, beneath the rear bolster support, said rect.' shatt having depending arms 55. A brale beam 57 has pivot connections 53 with the arm 5G, and is provided at its ends with brake shoes 5S) cooperating with the rear wheels. A lever GO is tulcrinned as shown at 6l, on one side of the center har tl, one arm of this lever cooperating with a raeh 62 secured to the rear axle, the other arm having an adjustable link connection G3 with the brake beam.

Perhaps the most important feature ol' the invention is the connection -between the. truel-s. As already stated und disclosed, the reach or coupling is pivoted to the trent truck directly i-eneath the l'ront bolster, und therefore no matter how much the l'ront truclr may le turned, the 'ront tolsier will remain the saine distance away l'rom the rear bolster, and there is no shitting of the load upon said holsters, that the oxjeetiimahle consequences due to said shitting` are, entirely coriated. At the same time, the, movement of the iront lolst er is entirely independent of the reach or coupling, and the advantages therefor have already leen fully set forth. Furthermore, the reach or coupling can be lengthened or shortened to suit the diilierent requirements ol use, und

encounter more resistance and strain in striking obstructions than the rear wheels. By employing the bolster supports, the frame is reinforced and the strain is better transmitted to the frame when the different Wheels of the ,vehicle dropintoruts and the like. The tracks or as they control the rocking motion of the bolster, especially `when making short turns, and if the road is at all inclined.. Y

Y From the foregoing, it is thought that the construction, operation, and many advantages of the herein described lnventionwill be,`

apparent to those skilled in the art` without furtherl description, and, it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departingfrom the spirit or sacricing any of the advantages j of the invention.

Having thus fully described my invention, what I claim as new, andV desire to secure by Letters Patent, is
